Output Short-Circuit Duration ...................................Continuous
Continuous Power Dissipation
WLP (derate 53.85mW/ N C above +70 N C)......................2.15W
Operating Temperature Range .......................... -40 N C to +85 N C
Junction Temperature (Note 2) .......................................+110 N C
Storage Temperature Range............................ -65 N C to +150 N C
Bump Reflow Temperature (Note 3) ...............................+260 N C
Note 1: LX has internal clamp diodes to GND and IN. Applications that forward bias these diodes must take care not to exceed
the IC’s package power dissipation limits.
Note 2: Limit the junction temperature to +110 N C for continuous operation at maximum output current.
Note 3: The WLP package is constructed using a unique set of package techniques that impose a limit on the thermal profile the
device can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder pro-
files recommended in the industry-standard specification JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection
reflow. Preheating is required. Hand or wave soldering is not allowed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
PACKAGE THERMAL CHARACTERISTICS (Note 4)
WLP
Junction-to-Ambient Resistance ( B JA ) ……………..25.5 N C/W
Junction-to-Board Thermal Resistance ( B JB )………18.5 N C/W
Note 4: Package thermal resistances were obtained using the MAX15112 evaluation board.
DC ELECTRICAL CHARACTERISTICS
(V IN = 5V, see the Typical Operating Circuits , T A = -40 N C to +85 N C. Typical values are at T A = +25 N C, unless otherwise noted.) (Note 5)
